How can you make sidebars translucent in Reeder and Tweetbot?

[Shawzborne]

Hi Everyone,

I was wondering if there is a way to make the sidebars in Tweetbot 2 for Mac and Reeder 3 translucent as you can see in these screenshots. Yes I know there is a toggle in Reeder 3 but it doesn't seem I can see through it or see the colours behind the window.

Tweetbot 2

Reeder 3

Thank-you,

Shawn

Maybe your gpu is not supported because for me works without any option...
